    NAME

    xencrypt, xdecrypt, passwd2des - RFS password encryption
     
    

    SYNOPSIS

    #include <rpc/des_crypt.h>

    void passwd2des(char *passwd, char *key);

    int xencrypt(char *secret, char *passwd);

    int xdecrypt(char *secret, char *passwd);  

    DESCRIPTION

    The function passwd2des() takes a character string passwd of arbitrary length and fills a character array key of length 8. The array key is suitable for use as DES key. It has odd parity set in bit 0 of each byte. Both other functions described here use this function to turn their argument passwd into a DES key.

    The xencrypt() function takes the ASCII character string secret given in hex, which must have a length that is a multiple of 16, encrypts it using the DES key derived from passwd by passwd2des(), and outputs the result again in secret as a hex string of the same length.

    The xdecrypt() function performs the converse operation.  

    RETURN VALUE

    The functions xencrypt() and xdecrypt() return 1 on success and 0 on error.  

    VERSIONS

    These routines are present in libc 4.6.27 and later, and in glibc 2.1 and later.  

    BUGS

    The prototypes are missing from the abovementioned include file.
